TIRE ARMOR AND .ANTISKID DEVICE.

Application filed February 24, 1921.

To all whom it may concern:

Be it known that I, ALBERT REMAR, a citizen of the United States of America, residinfr at Maynard, in the county of Belmont and tate of Ohio, have invented certain new and useful Improvements in Tire Armor and Antiskid Devices, of which the following is a specification.

This invention relates to certain new and useful improvements in tire armors and anti-skid devices wherein a plurality of connected metallic plates are assembled in inclosing relation on the tread surface of a tire with anti-skid ribs formed integral with the outer face of the plates with means for anchoring the assembled plates to the rim flanoes of the wheel.

Vffith the above general objects in view and others that will become apparent as the nature of the invention is better understood the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views,

Figure 1 is a top plan view of a portion of the tire armor and anti-skid device showing the connected plates provided with antiskidding ribs,

Fig. 2 shows by dotted lines a fragmentary side elevational view of a tire with the present invention in operative position thereon,

Fig. 3 is a cross sectional view taken on line III- III of Fig. 2 showing the armor anchoring hooks and the transverse antiskid ribs,

F iv. 4 is a cross sectional view taken on line `iv 1'v of Fig. 2 Showing the tread plates engaging the tread portion of the tire,

Fig. 5 is a detail perspective view of a portion of the armor,

Fi 6 is a cross sectional view taken on line I-VI of Fig. l, showing the hinge connections between the armor plates,

Fi 7 is a cross sectional view taken on line TII- VII of Fig. 1 showing the screw pins for connecting the armor plates, and

Fig. 8 is a perspective view of one of the armor plates showing the tread rib and the side sookets for the hinge blocks.

Referring more in detail to the accompanying drawings there is illustrated a tlre armor and antiskid device formed of a plu- Specification of Letters Patent.

ralityiof rhombus-shaped metallic plates l i transversely curved coincident to the curvature of the tread portion of the tire a as shown in F igs. 3 and 4 with the longitudinal axes of the plates l when assembled, extending circumferentially of the tire a as shown in F igs. l and 2. Each plate is provided with a transversely extending antiskid rib 2 forming an integral part thereof, ribs 2 extending between the obtuse angled corners of' the plates asshown in Figs. 1; 2 and 8.

The plates l forming the armor are hingedly connected at their adjacent edges, the edges of the plates l 7being cut away termediate the ends thereof as at 3 -with curved bottom walls 4 as clearly shown in Figs. 6 and 8. Hinged blocks 5, of the form best illustrated in Figs. 5 and 6 having curved side walls are received in the cut out portions 3 with the opposite edges thereof engaging the curved bottom walls 4 of the adjacent plates 1, the edges of the plates l being provided with longitudinal openings 6 that register with openings 7 in the blocks 5 as shown in Fig. 7 into which screw pins 8 are received for retaining the plates 1 in assembled relation as shown in Figs. l and 2. To retain the armor on the tread of the tire a the outer corner edges of the laterally positioned plates 1 are provided with lugs 9 that are secured to the adjacent ends or V- shaped brackets 10 by studs 11, the brackets being curved as shown in Figs. 2 and 3, coincident to the curvature of the side wall of the tire a with the inner ends 12 of the brackets pivotally supported in hooks 13. The hooks 13 are reversely curved as shown in F igs. 2 and 3 for engaging within the rim flanges c and the tire beads b, the hooks 13 securely anchoring the tire armor on the tire a.

The hinged blocks 5 connecting the plates 1 have the opposite faces thereof lying substantially flush with the opposite face of the plates so that injury to the tire will be entirely eliminated while the antivskidding ribs 2 are alone presented for earth gripping to prevent skidding of the wheel. The connection between the plates l will permit free fiexible movement thereof to compensate for varying pressures on the tire a with the result that the armor will snugly engage the outer surface of the tire at all times irrespective of different loads placed thereon. While there is herein shown and described the preferred embod'nnent of the present inture of a tire, With the longitudinal axes of Vention, it is nevertheless to Vbe nnderstood the plates extending circnmferentially of that minor changes may be 'made therein the `tire ribs extendin'g between the obtuse Without departing froni the spirit andscope angles of .said ,plates, hinge connections beof the invention as claimed. tween adjacent edges of the plates, means What is claimed as new is z- V for anchoring the plates to a tire, said 1.
